Not clear as to why this was requested - I guess because I've had some winnings (up ~1k USD)?
Maybe they are checking your bets to know whether you have manipulated the game or not. Because you are continuously making profit in Crashino.com

.
Appears you have been online today (kudos for updating the topic) and any sort of response would be appreciated
I hope they will give an update about your issue by tomorrow. It is good that they have updated the main post and removed the "No KYC" part from there.
Thank you @OP for removing the misleading information from the title.
